Bourns 9220-16 560µH Inductor: Equivalent & Substitute Parts

Part Overview

The Bourns 9220-16 is a 560 µH unshielded drum core wirewound inductor rated for 91 mA maximum current with 12.3Ω DC resistance. Designed for through-hole axial mounting, this component operates across the -55°C to 105°C temperature range. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, repair, and redesign applications where the original part is no longer available from primary sources.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 9220-16 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Inductance value: 560 µH
• Inductance tolerance: ±5%
• DC resistance: 12.3Ω Max
• Shielding configuration: Unshielded
• Mounting type: Through Hole Axial
• Operating temperature range: -55°C to 105°C

Allowable Variation:

• Current rating: Substitute must meet or exceed 91 mA minimum
• Core material: May differ (ferrite or iron) provided all electrical parameters are maintained
• Physical dimensions: May vary within through-hole axial package constraints
• Packaging format: May differ (tape & reel acceptable for through-hole components)

The API Delevan 2500-16J satisfies all mandatory parameters and exceeds the current rating requirement (104 mA vs. 91 mA), qualifying as a direct functional substitute.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan 2500-16J is electrically and functionally equivalent to the obsolete Bourns 9220-16 based on matching inductance, tolerance, DC resistance, shielding, temperature range, and mounting configuration. The substitute component provides higher current capacity (104 mA vs. 91 mA), which represents an improvement for the specified application.

Physical dimensions differ: the API Delevan part is larger (0.240" diameter × 0.740" length versus 0.190" diameter × 0.440" length). PCB layout and mechanical clearance must be verified before implementation. The API Delevan 2500-16J is currently active in production, ensuring availability for new builds and ongoing supply.

Both components carry identical RoHS non-compliance and REACH unaffected status. No compliance advantage exists between the two parts.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 2500-16J be used as a direct replacement for the Bourns 9220-16?

A: Yes, from an electrical standpoint. The substitute matches all critical electrical parameters: 560 µH inductance, ±5% tolerance, 12.3Ω DC resistance, unshielded configuration, and -55°C to 105°C operating range. Physical dimensions are larger, requiring verification of PCB layout and mechanical clearance.

Q: What is the significance of the different core materials (ferrite vs. iron)?

A: Both ferrite and iron cores achieve the specified 560 µH inductance and 12.3Ω DC resistance. The core material difference does not affect electrical performance for this application, provided all measured parameters remain within specification.

Q: Why is the API Delevan part larger physically?

A: Different core geometries and winding configurations between manufacturers result in different physical packages. Both parts maintain identical electrical specifications through different design approaches.

Q: Does the higher current rating of the API Delevan part (104 mA vs. 91 mA) affect circuit operation?

A: No. A substitute with higher current capacity is acceptable and does not degrade circuit performance. The circuit will operate within the substitute's rated limits.

Q: Are there any compliance or certification differences between these parts?

A: Both parts share identical RoHS and REACH status. No compliance advantage exists between the two components.

Q: What is the primary reason to consider substitution?

A: The Bourns 9220-16 is obsolete and no longer manufactured. The API Delevan 2500-16J is an active production part, ensuring availability for repair, redesign, and new applications.
